1 PAT100 SERIES Handheld portable appliance testers PAT100 SERIES Handheld portable appliance testers Simple Tick/Cross, pass/fail indication plus measurement Battery powered with rechargeable options Includes 250 V Insulation and Leakage testing for safe IT testing and surge protected devices Testing portable and fixed electrical equipment 10 ma and 30 ma Portable RCD lead testing (PAT150) Adjustable PASS test limits (PAT150) Substitute and Mains powered leakage testing (PAT150) Tough, rubber armoured with built-in front cover, hardened, scratch proof display window Description The PAT100 series of hand help portable appliance testers enable simple, fast safety testing in all environments including offices, shops and business units. It is ideally suited to training organisations with a very short learning curve and tough, reliable functionality. With rubber armoured cases and fitted with hardened, scratch proof glass, the PAT100s are exceptionally tough instruments. Battery powered operation makes the PAT100s perfect for those locations where an electrical supply is not available, inconvenient or unsafe, especially building sites and warehouses. The PAT100 series conforms to all and European requirements for electrical safety testing. Test groups Test groups enable the correct sequence of tests to be performed automatically with minimum intervention by the user. This keeps testing simple, reduces test times to a minimum and helps to prevent testing errors. PAT120: The PAT120 model has test groups available for Class I, Class II and Extension/Power leads. Fixed PASS limits. Insulation testing at 500 V (default) or 250 V can be selected at the start of the test. Leakage testing uses a Substitute Leakage also known as the Alternative method to remove the need for a mains supply during test. The PAT150: The PAT150 has additional tests available for testing portable RCDs (PRCDs) of 10 ma and 30 ma. Separate tests for Continuity, Insulation, mains powered leakage testing and SELV measurements can be made using the Quick Test (QT) button. Test group pass limits and test duration can be configured by the user. Bond lead resistance can be nulled to reduce measurement errors. Live circuit measurement is available for testing the mains supply and socket polarity or electrical circuit voltage to 300 V ac. Can be used for testing fixed appliances. Continuity test Used for measuring the proper bonding of all metal parts of a class I device to the protective conductor. Tests are performed at 200 ma dc in both polarities to be compliant with international and regulation or recommendations. This test is safe to perform on equipment where higher test currents could cause damage. Insulation testing Used for measuring the separation of conductive parts or conductors from earth. This test is usually performed at 500 V dc. The PAT100 series maintain the necessary test voltage down to 0.5 Mohms.

2 An additional 250 V dc insulation test is available on all models for use on IT equipment, on devices or extension leads that are fitted with surge protection, or simply where it may be considered undesirable to use a 500 V test. Substitute leakage testing Substitute leakage testing enables the measurements of AC leakage currents, which could differ significantly from the DC Insulation test results. Substitute leakage testing is performed at less than 40 V ac. and does not require a mains supply. Substitute leakage testing is used for measuring protective conductor current and touch current, in addition to an insulation test, or where it is considered an insulation test may damage equipment. The Substitute leakage test will not operate equipment and so can be used where the operation of the equipment under test is undesirable. Portable RCD testing (PRCD) Portable RCDs can be tested using the PAT150. There is no need to find a non-rcd protected supply as the PAT150 will not trip external RCDs. Both 10 ma and 30 ma RCDs can be tested both for disconnection times and the manual test button function. Separated Extra Low Voltage (SELV) supplies SELV supplies should be tested to ensure the output voltage does not exceed maximum limits as defined in the international regulations for Extra Low voltage systems. The PAT150 permits up to 50 V ac measurement, with a PASS or fail indication for SELV. Differential Leakage (Protective Conductor Current), Touch Current & operational test The PAT150 includes the facility for mains powered leakage test. This test has the benefit that equipment under test will function during the test sequence. Battery life The PAT120 & PAT150 operates from AA Alkaline or NiMH cells. Battery life is typically 4 days, based on 120 assets per day. The PAT150R can be re-charged with NiMH batteries fitted.
